Content Ratings

No Romance
There is no romance; Lina and Doon's relationship ends where it began, as a warm and valued friendship.
Mild Themes
The importance of knowledge, the courage to retrieve what has been lost, and the hope that past ingenuity can improve the present are the novel's primary themes.
Mild Violence
Encounters with roamers—dangerous nomadic survivors—and the instability of Ember itself create tension; violence is limited and adventure-appropriate.
Synopsis

Lina and Doon return to Ember on a dangerous journey to retrieve a lost book that may hold technology capable of improving life in Sparks, while facing roamers and the danger of the city's failing electrical system. The concluding volume of the main Ember narrative ties up the story of Lina and Doon with warmth and adventure.
